Finding php.ini: WordPress Configuration Troubleshooting

In this short article, we will discuss the different options you can use to find the php.ini file in WordPress. It's good to know where it is because sometimes you need to modify some settings in this file.

For example, you may see this error in a WordPress site:

"The uploaded file exceeds upload_max_filesize"

This tells you that the file you are trying to upload in WordPress exceeds the file size configured in the php.ini configuration file. Therefore, you may need to increase the maximum size in the php.ini file.

That being said, it also allows you to configure many other options related to PHP if you know the location of the php.ini configuration file.

php.ini What is the file?

First of all, you should know that WordPress is built on the PHP programming language. PHP must be running on the server every time a WordPress page is loaded. When PHP runs, it looks for the php.ini file in some specific location and loads it. This file configures how PHP works and has a huge impact on PHP software like WordPress.

Of course it's possible that you never need to modify php.ini. PHP can run happily using the settings provided in the default php.ini file because PHP comes with these default recommended settings. In fact, running PHP does not require setting any key configuration parameters.

However, the php.ini file provides some important settings that you need to be familiar with. In fact, it is inevitable for PHP developers to encounter it sooner or later.

How to find the php.ini file in WordPress

In this section, we will learn how to find the php.ini file that is loaded when running WordPress. This can be tricky - the location of the php.ini file varies depending on the environment in which PHP is running.

The best way to know the location of the php.ini file is to use the phpinfo() function. It will tell you where php.ini is located and also print out all the important PHP configuration information.

You can run phpinfo() by creating a .php file and calling this function. Proceed to create a phpinfo.php file with the following content and place it in the document root.

<?php
phpinfo();
?>

Now upload this file to the root directory of your WordPress installation. Next, run the https://your-wordpress-site.com/phpinfo.php URL in your browser and you should see the output of phpinfo(). Find the sections below.

As you can see, there are two parts. The first configuration file (php.ini) path represents the default path of the php.ini file in the system. The second, Loaded configuration file, is the path to the php.ini file loaded when PHP is running.

So you can edit the php.ini file indicated in the Loaded Configuration File section and this should work in most cases. Once you have determined the location of the php.ini file, don't forget to delete the phpinfo.php file from the site.

If you cannot access the location of the php.ini file, you can try the solution described in the next section.

Use cPanel to find the php.ini file

In this section, we will learn how to edit the php.ini file to WordPress with the help of cPanel. Of course, you need cPanel access on your hosting to use this option!

Continue logging into your cPanel. On the dashboard, you should be able to see the following options.

Next, click on the File Manager link on the dashboard, which will take you to a screen that lists the files on the server. Navigate to the WordPress root installation directory. It should display a list of files as shown in the screenshot below.

Now, try to find the php.ini file in the list, if it does not exist, you can create a new file in the document root directory.

How to fix upload_max_filesize Error

In this section, we will learn how to fix the upload_max_filesize error. Once you have found the location of your WordPress site’s php.ini file, you can simply change the following settings in the file.

upload_max_filesize = 64M
max_execution_time = 300
memory_limit = 128M
post_max_size = 64M
max_input_time = 300

If you are editing an existing php.ini file then just change the values ​​as per your requirement. On the other hand, if you created a new file, you need to add it.
